Our invention has relation to machines for the manufacture of drain-tile and similarware, and has for its object to simplify the construction of machines of that class, as well as to facilitate the operation of manufacturing tile. To this end our improvement consists, first, in the combination,withafeed-chamber, which 5o may be of any suitable shapeand construction for feeding the clay through the dies or molds,

frame, showing the adjustable box or bearing Fig. 9 is a plan or top iof two or more crusher-rollers for crushing the clay, which said rollers are operated by the same gearing and mechanism which opermachine proper, all as hereinafter more fully described.

On the accompanying seven sheets of drawings, Figs. 1, 2, and 13, show the complete machine-that is, the combined clay-crusher and tile-machine, as we prefer to construct it while the remaining figures refer to details of construction. Inthe said figures, F denotes the mainframe or bed of the machine, which is mounted upon legs f of suitable height. This frame is provided at its rear end with a fixed boxor shaft-bearing, A, and at its front end with an adjustable box or shaft-bearing, A, the construction of which is illustrated more clearly in Fig. 5 of the drawings, from which it will be seen that the box is fitted loosely into a recess, a, in the front end of the frame, and fastened to the same by means of threaded bolts b b. The threaded ends of these bolts are inserted through oblong slots or apertures c in the wings .or lateralexten' sions d of the box, thusjpermitting of lateral screws 6 0 box A may be adjusted in frame F,

so as to be in a line with the fixed box A at the opposite end of the frame, whereby we are enabledto regulate the exact position of the main. shaft within the feed-chamber or clayreceiver K. This chamber (shown at- K in the drawings) is provided with lateral wings or extensions k, which rest upon and are bolted to the rearwardly-extending arms F F of frame F by bolts inserted through the boltholes f. Chamber K has an opening, K, in the top, and its front end, which extends out over frame F, is provided with a flange or collar, K for the attachment of the neck or extension H, which is fastened removably upon the collar K by bolts or screws h, inserted' through the flanges. The molds or dies are fastened to the front end of the extension H by means of brackets H and screws h, inserted through said brackets, as shown more clearly in Fig. 13 of the drawings. Inserted through the bottom. of the feed-chamber are studs or knives S, fastened to the under side of the chamber by nuts 8. These studs or knives operate to cut and mix the clay as it is forced against them by the revolution of the sectional spiral or feed-auger N. This feed-spiral is shown in detail in Figs. 10 and 11 of the drawings, from which it will be seen that it consists of a series of spiraled propeller-shaped blades fastened upon and projecting from opposite sides of collars N, fitting upon the squared main shaft G and kept at the proper distance apart from one another by collars or tubular washers 0. These collars are of such a width as to space the propeller-collars N sufficiently far apart from one another to permit their flanged spirals or propeller-blades to pass on opposite sides of the fixed studs or knives S, without touching the same, by the revolution of the shaft, as will appear more clearly by reference to Fig. 11 of the drawings.

In order to prevent the clay from adhering to the erusher-rollers It R, which are mounted above the feed-chamber, we provide the top partof said chamber with adjustable scrapers I, provided with screw-threaded lugs t, through which adj listing-screws I are inserted, the heads of which bear against wedge-shaped blocks 1 fastened upon the lateral wings or extensions -kof the feed-chamber. By adjusting the screws I, it will be seen that thescrapers I maybe moved so as to bring their beveled edges in contact with the rolls It, so as to take up wear as the scrapers are gradually worn away by the revolution of the rolls.

Clay is fed to the f eed-ehamber through the aperture K. in its top part, which is below and-in a line with the crusher-rolls R, where these face each other, as will appear more clearly by reference to Fig. 6 of the drawings. The clay is fed to these rollers through a hopper, L, and thej ournal-boxes O of the crusherrollers are made adjustable in the end plates, 0', in substantially the same manner as shown in Fig. 5 for the lateral adjustment of box A, whereby the rollershafts P may be properly adjusted relative to each other, so as to bring their respective rollers R the proper distance apart, and thus crush or comminute the clay to the required degree of fineness.

By reference to Figs. 9 and 12 on Sheet 6, it will be seen that the main shaft G has an extension, G,'npon which is keyed two cogwheels, 9 and G. The smaller of the two, 9, meshes with the gear-wheel Q upon the projecting end of one of the roller-shafts'P, while the large gear-wheel G meshes with a pinion, T, keyed upon shaft U, which has its bearings upon boxes on the top of plate F, and the outer end of which is provided with a drive-pulley, V. Thus it will be seen that when pulley V is rotated by an endless belt from a steamengine, or any other suitable motive power, the crusher-rollers are caused to revolve toward each other, as indicated by the arrows in Fig, 6, at the same time that the feed mechanism is operated.

From the foregoing description, taken in connection with the drawings, the working of our improved machine will readily be understood without requiriug extended explanation. Clay being thrown into the hopper is seized by the rolls as these revolve toward each other, and drawn through between them, thus crushing small stones, lumps, and other substances contained in the clay, and otherwise crushing, grinding, and preparing the same for being molded into tile, bricks, or other ware. But besides crushing and preparing the clay, it will be seen that the rollsalso operate a; feedrolls or force-rolls tofeed and force the crushed clay through the aperture K into the feedchamber K, where it is met by the feed mech anism, which feeds the clay out through the extensionK neck H, and the dies or molds which are fastened at the front end of the lat ter. The studs or knives S prevent the clay from revolving with the feed-spiral, and also serve, as hereinbefore stated, to cut the mass of clay, and thus assist in its thorough mixing into a homogeneous mass before it reaches the dies or molds at the outer end of the chamber. There may be one, two, or more rows or series of these studs fastened to the bottom and inner sides of the feed-chamber, and we desire it understood that we do not limit ourselves to only one row, as shown in the drawings.

lVhilc we prefer to use only two crusherrollers and arrange them as shown in the drawings, thereby causing them to force-feed the crushed clay into the feed-chamber in the man ner hereinbefore described, it is obvious that there may bejmore than two of these rollers, and that they may be located at a higher distance above the feed-chamber, so as to drop the crushed clay into the same without any forcefeed, or into a chamber or receptacle placed between the crusher-rollers and the feed-chamher; but we prefer the arrangement shown in the drawings for the reason that by forcing the crushed clay into the feed-chamber and into direct contact with the feed mechanism it facilitates the operation of the machine and produces a better article by compacting the clay more solidly than can be done by the feed mechanism alone. I

Having thus described our invention, we claim and desire to secure by Letters Patent of the United States 1. The combination, in a tile-machine, of the frame having the fixed shaft-bearing A and a recess, a, near the feed-chamben'the adj ustable box A, having slots 0 in its wings or extensions and inclined sides, bolts b, sliding in said slots, set-screws 6, bearing with their' ends against the inclined sides of box A, and the feeder-shaft G G", as and for the purpose shown and set forth.

2. The combination of the feed chamber having a longitudinal opening at its upper side and laterally-projeoting extensions k, the crusher-rollers, the beveled blocks 1 upon the extensions, the scrapers having-female-threaded perforated lugs 'i, and the set-screws I, as and for the purpose shown and set forth.

3. In a tile-machine having a cylindrical feed-chamber, the combination of a revolving shaft, collars secured upon the shaft and provided each'with two spiral flanges having a twist of one-half revolution in opposite direclions, and having the ends cut off perpendicular to the shaft, spacing-collars inserted between the flanged collars, and knives or studs inserted'in 'the bottom of the feed-chamber 15 and projecting up 'in and nearly filling the spaces between the perpendicular ends of the flanges, as and for the purpose shown and set forth.

In testimony that We claim the foregoing as 20 our own we have hereunto affixed our signatnres in presence of two witnesses.
